DISK PLOW.

Patented Aug. 29, 1911.

Serial No. 605,443.V

To all whom tt may concern:

-Be it known that I, BARNET N. BoT'rs, citizen of the United States, residing at Paso Robles, in the county of San Luis Obispo and State of California, have invented new and useful Improvements in Disk Plows, of which the following is a specification.

This invention relates to a disk plow and particularly pertains to a disk plow in which the disks are reversible. A

It is the object of this invention to provide a disk plow in which the disks are adapted to operate on a hillside or on level ground, and which is so constructed that it will perform the plowing functions when traveling in a forward or reverse direction.

A further object is to provide a disk plow in which the angle of the disks in relation to the line of draft may be reversed so that the directionI of travel of the plow may be reversed without turning the plow carriage and yet obtain the same plowing efficiency.

Another object is to provide a novel means for reversing the disks which is simple in construction, substantial, and positive in'its operation, and means by which the disks may be lifted clear of the ground, means being also provided for retaining the disks in their uppermost positions, so as to render them inoperative when it is desired to move the plow from one point to another without plowing.

The invention consists of the parts and the combination and construction of` parts as hereinafter more fully described and claimed,`having reference to the accompanying drawings, in which- 'Figure 1 is a plan view of the plow as positioned to travel in one direction. Fig. 2 is a similar view showing the plow as reversed. Fig. 3 is a detail in perspective o f the disk carrying arm. Fig. @L is a detail vertical section on the line X X, lFig. Fig. 5 is a side elevation. Fig. 6 is a detail plan view illustrating a modified form of mounting the furrow wheels.

In the drawings, A represents the draft beam or truck which may be formed of a rectangular bar or a channel iron, the outer ends of which are supported upon alined wheels 2 2. A laterally extending segmental frame A mounted on the beam A forms a bracket on which is mounted a vertically adjustable outrunner or wheel 3,

6 rigidly secured to and de endin f the underside of the bracket AP. g 10m A link 7 is pivoted at one end on the stud 4; and has its opposite end pivotally connected to the lower end of an arm 8 mounted on the end of a rock shaft9 which extends beneath the bracket A and beam A, and is supported in suitable bearings thereon. The outer end of the shaft 9 is provided with an upwardly extending lever arm 10 having a handhold on its upper end by means .of which the lever may be swun from side to side so as to rock the shaft 9 and thereby raise and lower the block 5 through the .linked connection 7. A notched segment 11 is mounted on the beam A adjacent the lever arm 10, the notches of which are adapted to be engaged by a pawl 12 on the lever 10 to retain the latter in a fixed position in the manner common to machines of this character; the pawl 12 being released from the notched segment 11 when it is desired to operate the lever 10. When the lever 10 is in its extreme position on either side of the center of the segment 11, the block 5 and the wheel 3 thereon, are in their uppermost position, and when the lever 10 is vertically disposed in line with the center of the segment 11, the block 5 and the wheel 3 will be in their lowermost position. In the latter case the beam or truck A will be disposed in approximately a horizontal position if the wheels 2-2-3 are on a level surface.

Mounted near the ends of the beam A are downwardly curved hangers 13. The ends of these hangers 13 extend horizontally toward the center of the beam and form bearings for vertically disposed rotatable studs 141 rigidly mounted at their lower ends on curved arms 15, as shown in Fig. 3, which are adapted to be swung from side to side on the hangers 13, as later described.

The outer end of each arm 15 carries a dished disk 16 which is vertically disposed and revolubly mounted at its center on the arm 15, the disk 16 being arranged to face in corresponding directions with one disk located -to the rear and to one side of the other, as shown in Fig. 1; the faces of the disks being adapted to be swung into angular relation with the beam A by the operation of the stud 14.

The upper end of each stud 14 extends g', through the beam A and has a horizontally extending arm 17 rigidly mounted on 'its 'in its uppermost position, the disks 16 Vare upper end. 'Pivotally connected at one end to the outer end of each arm 17 is a'curved link 18, the other end of which is pivotally a connected to oppositely disposed crank-arms 19 formed on and integral with the inner end of a tongue or sweep 20, which is pivoted on a stud 21 at a point midway between the pivotal connection of the links on the arms 19. The stud 21 is securely mounted on the beam A midway of its length and projects upward therefrom a suiiicient distance to form a substantial bearing for the tongue 2O swiveled thereon. The tongue 20 H normally extends in a horizontal direction parallel to and in alinement with the beam A, being of suiiicient length to project a short distance beyond the end thereof, and having a loop on its outer end to receive the clevis pin of a whiflie-tree, not shown.

Means are provided for securing the tongue 20 in alinement with the beam A, which means is here shown as consisting of a dog 22 which is pivoted on the tongue and adapted to extend through a perforation in a lip formed on an abutment plate 23 on the beam A, the dog 22 being operated through a foot plate 24 thereon. Mounted on the tongue 20 is the drivers seat 30 which may be of any suitable description.

When the tongue 2O is parallel with the beam A as shown in Fig. 1, the disks 16 will bedisposed at an angle to the beam in such position as to have a plowing action when the plow is drawn in the direction, indicated by the arrow X. By disconnecting the tongue 20 from the beam and swinging it on its pivot 21 one half a revolution, so as to dispose it in the position shown in Fig. 2, the arms 15 and disks 16 will swing beneath the beam A into an angular position in relation thereto opposite that shown in Fig. 1,

in which position they will perform a plowing action when the plow is moved in the di 50 rection indicated by the arrow Y.

From the foregoing it will be seen that when the end of a furrow is reached, traveling in either direction, the plow is reversed by merely swinging the tongue from one end to the other, thus reversing the plow withoutdisturbing the running gear or the plow beam.

As the outer disk receives the greatest strains on its front edge when plowing, tend- 60 ing to swing the arm 15 backward, means are provided for limiting t-he backward swing of the arm and also for relieving the arm 15 and stud 14 and its connections from a portion of the strains. This means resides in forming an upwardly projecting lug or shoulder 25 on the arm 15 which is adapted to contact and bear against an abutment 26 formed on the hanger 13, as shown in Fig. 3, when the arm 15 is swung into its outermost position.

Vhen the third wheel or outrunner 3 is in such a position as to cause approximately two-thirds of the lower portion of the disks to enter the ground. When it is desired to reverse the disks, the wheel 3 is lowered as before described, so as to elevate theplow beam A and thus lift the disks clear of the ground, this being also done when the plow is to be hauled from one plowing. t

In constructing a plow on the foregoing principles which is to be particularly employed as a hillside plow, the alined wheels 2 2 are preferably mounted on steering knuckles, as shownin Fig. 6, in 'which case an armv 27 mounted on the knuckle in the usual manner is connected by a link 28 to an arm 29 on the link 17 adjacent the stud 14, so that when the tongue 2() is in a straight ahead position, the wheels 2-2 are thrown into an angular position in relation to the beam A asindicated in dotted lines in Fig. 6. Theobject of thus disposing the wheels 2-2 at an angle to the line of draft, is to. cause them to have a climbing action when the plow is drawn across a. sloping surface, as is common in machines of this character.
